Like yarrow spreading only where roots take hold, reputation grows gradually and cannot be bought instantly. An attacker spinning up thousands of sock puppets would need to fund each stake, wait out the vesting period, and do real useful work before gaining influence, making a large-scale Sybil attack slow and expensive while honest newcomers still join cheaply.","stamp":4,"from":"poa12D8S6YEbkgr16XGAfrjmatjYd7pbpbgVsUA4Y8HMLYdn","nonce":8,"parents":["d13042616c5074084948620c8ea5fd4cd12de3add0fba1f9d9851744d8ac6a4a","2646fe1464ff6d09285bb0ed60f17631cc94df4cc1082348c7566fc1289e793a"],"ts":1793048212,"cid":"poa-mainnet-1","sig":"2vv9NbtXSn2K9WAdVV21q9yqTpQXRyHZmF7cB7hjwX1Yzyj85nqSTdUdvfvHYYC5FnfbtFeNfyT4foCaGExZ61K5"},"checkpointed":{"height":87024,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T08:01:56.230Z","checkpoint_height":87024,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
